Working principle
Positive Pressure Ventilation
• Introduce fresh air to generate positive pressure, continuously provide fresh air to the room. Users can enjoy the fresh air without opening the window, and ensure the oxygen content and freshness of the indoor air.
Preheating
• After it connects to air to water heat pump or boiler to preheat outdoor inlet fresh air. Improving the comfort of fresh indoor air in winter
Our fresh air ventilation system can be connected to the boiler or air to water heat pump system to achieve the role of pre-cooling and preheating outdoor inlet fresh air.
Internal Circulation Mode
• Primarily designed for extreme low-temperature environments, this mode intelligently switches between fresh air mode and internal circulation operation logic based on indoor temperature. While ensuring basic indoor air circulation, it significantly reduces heat loss caused by drawing in frigid outdoor air in such harsh conditions, thereby minimizing the overall energy consumption of both indoor heating systems and the unit itself.
Intelligent antifreeze
• When the outdoor temperature is lower than the set value, it automatically switches to smart mode, automatically switching between internal circulation and fresh air mode.
Controller
Through high-precision sensors, real-time display of outdoor fresh air temperature, wind speed, time and other indicators. According to the outdoor fresh air temperature, the electric auxiliary heating is intelligently activated to preheat the outdoor temperature and improve the comfort of the fresh air.
